2. CURVE SHOWS REDUCTION IN TRANSFORMER SECONDARY VOLTAGE
AND DRIVE MODULE INTERNAL DC BUS VOLTAGE, DUE TO TRANSFORMER
INTERNAL LOSSES, AS BUS CURRENT LOAD INCREASES.
(NOT ACCESSIBLE TO THE USER).
3. ALL DATA TAKEN WITH TRANSFORMER PRIMARY VOLTAGE HELD
TO 230 VAC 1 PHASE LINE TO LINE 60 Hz AND WITH SECONDARY
WIRED FOR 230 VAC LINE TO LINE NO LOAD.
DC BUS VOLTAGE AND CURRENT IS MEASURED AT MOTOR POWER
